Hi Melanie,
Apologies for my delayed response.
I believe in the past the m3u8 format has been troublesome for Jaksta. Are you able to provide a link to the problem video?
If login credentials are required to access the video you can send them privately to us at support@jaksta.com, so long as you are comfortable with it.

Is there a way to download videos in this format using jaksta? Mhel
